This invention relates to an improved repeating rifle and has as one of its objects to provide a repeating rifle by which a greater number of cartridges may be successively flred than by the use of the ordinary repeating rifle embodying the usual shiftable cartridge carrier.

The rifle embodying the invention is pro.

vided with a cartridge cylinder which is I rotatably mounted upon the stock of the rifle tive chambers, so that notwithstandingthe fact that the cap ends of the shells are exposed at the rear side of the barrel there is no likelihood of the shells being accidentally displaced from the chambers of the barrel,

" and in this connection the invention also contemplates a novel means whereby the shell chambers may be readily released when it is desired to cleanse the same. 7

Another object of the invention is to proide a novel means whereby intermittent rotary motion will be automatically imparted to the shell barrel each time the trigger of the rifle is pulled, so that by merely pulling the trigger. a successive number oil-times, as many shells as desired may be successively discharged in rapid order.

Another object of the invention is to provide a novel firing pin for the rifle which pin may be readily dismounted and a new pin substituted. therefor without necessitating any separation of the parts of the rifle or a dismounting of the same, except for the removal of thecarrier-for the pin.

Another object of the invention is to provide a novel means for locking the cartridge cylinder in its successive positions of ad yustment, so that each cartridgewlll, in order, be present 1n'd1rect aX1al allnement with the barrel of the rifle, preparatoryto being discharged. I

This invention also consists in certain other 7 features of construction and in the arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view in side elevation of a rifle constructed in accordance with the present invention. 7

In thedrawings the stock of the rifle is indicated by the numeral l and the usual barrel by the numeral 2 and the said stock in: eludes a body member which may be cast or 'machined, and which is indicated ingenera-l by the numeral 3. At its forward end, the stock body 3 is exteriorly of slightly greater diameter than the butt end of the barrel 1 and the said body is formed at its said end with a bore 4 which receives the exteriorly reduced body end of the barrel, this end of the barrel being held in place by scre'ws 5.

Preferably the bore 4 is reduced at its inner end as indicated by the numeral 6 so as to accommodate the'furtherreduced body end portions 7 of the barrel, this end being j grooves 20 are formed which flush with the rear side of the reduced por tion 6. The stock body 3 is furtherrforrned with depending front and rear portions1ndicated by the numerals 8'and 9-respect1vely,

and a spindle lO is fitted through an, opening in the-portion 8 and threaded at its rear end in an opening inthe portion 9. The car tridge storing-barrel is rotatably mounted upona spindle 10 and the upper portion of the barrel rotates in a recess 11 formed in the upperi portion of the member 3.

The cartridge supporting and storing barrelislindicated in general by the numeral 13and the same comprises an annular rim 14 and short spolres'l-o which radiate from the sleeve like hub 16 which rotatably fits the spindle 10. A circumferential groove 17 is formed in the rim 14 of the barrel and the side walls ofithis groove arebeveled so as'to converge in the direction of the periphery of the rim as indicated by the numeral 18, and, asclearly shown in Figure 3 of the draw ings,--the forward side wall of the groove 17 is likewisebeveled as indicated by the numeral 19; This groove is continuous except that, at equi-distantly spaced points in the circumference of the barrel rim, short open through the rear side of the barrel rim and communicate atitlieir inner ends with the groove 17.

Lihesegrooves 20 are of a. width slightly greater than the diameter of one of the cartridge chambers, heretofore referred to, and

V the structure and arrangement of these chambers will now be described.

,1 flhe cartridge, chambers, referred to, are

shown clearly in Figures 5, 6 and 7 of the drawings, and-two kinds of chambers are employed and are alternately arranged.

One of these chambers, illustrated in F igures 5 and 6 ofthe'drawings'and indicated" in general by the numeral 21 is of cylindrical tubular form and interiorly of a diameter to accommodate a cartridge 22 of the usual type,wh1ch cartridge 1s preferably provided near its butt end with a circumscribing groove 28, which is pressed in the shell rhere'of Each of'the chambers is formed 1 cross sectionalv dimensions to adapt it to'fit:

upon what will constitute its inner side when the chambers are arranged'aboutthe" barrel 13 witha boss 24 having beveled ends 25 andbeveiedsides 26 andthis boss is of her as indicated by the numeral 27.

slidably through the groove 20 when the chamber 21 is slid into the groove 17. The

cartridge chamber shown in Figure"? is identical with the chamber shown in F igures 5 and 6 so far as the latter chamber has been described, except that'the rear end of.

the boss 24 thereof is not beveled, but in a plane at right angles to the aXisof the charm Therefore, this plane or straight end portion of the boss 2450f the said chamber shown in Figure 7 is adapted to seat in and fill the respective groove 20 which constitutes an eX- tension of the groove 17.

Each of the chambers 21 shown in Figures 5 and 6 is formed, near its rear end,:with a slot 28 extending a shortdistance about the circumference of the chamber andi-a similar slot 29 is formed in thatsid'e of the chamber shownin Figure 7 which is presented toward the side of the chamber shown in Figure 15, in the assembled alternate arrangement of .thetwo chambers, in which the slot 28 is formed, so that the slots 28 and 29,0f the two forms of chambers, site each other. shown in Flgures are 7 located oppo- 5 and 6 of the drawings,

' has mounted thereon "a locking means which pivotally comprises a: fiat sidedclever 30; mountedas at 31, upon the same side of the chamber as that in which the slot 28 is Each of the chambers 21,

formed, andthis lever is providedat its rear 7 end with a fiat sided lock head: .32 which is disposed in a plane at right angles to the plane of the lever and which therefore proje'cts beyond the opposite sides of the lever at its 'said rear end so thatits projecting edge portions will engage inthe slots 28 and 29 in the two chambers 21;and 21 whenthe lever is in the position shown in Figure 5 of chambers 21-held against the outward sliding movementof their bosses 24 through the grooves 20, but likewise the cart-ridges in the chambers are preventedfrom displacement.

Each lever EAhas a finger piece35 at its forward end, "and a tension spring 36' is con-- nected to an ear 37' providedat the lower edge of the lever belowandslightly forwardly of the pivot other end to:;the barrel 21 near the forward end thereof so that the lever30 isnormally' held inlthe lockingposition'shown' in Figure 5, it being understood, however, that byodev I pressing the forward end of each lever;

31 'and connected at its,

laai

bring its bosses 24 opposite the groove 20,

whereupon it too may be removed from the barrel.

The firing pin of the rifle is indicated by the numeral 38 and the same has its diameter reduced throughout its forward portion so as to provide a shoulder 39 against which bears one end of a compression spring 40 which is mounted in the bore of a bushing 41 threaded into a socket in the rear end of the stock 3, the other end of the spring bearing against the inner end of said bore and the bore being reduced at its inner end so as to accommodate the similar end of the firing pin, the pin being pointed at its extreme forward end as at 42 and projecting at its rear end beyond the said bushing 41.

This construction of firing pin and the manner in which it is mounted provides for ready removal of the bushing and removal of the pin in the event it is desired to replace the pin.

The hammer of the rifle is indicated in general by the numeral 43 and is provided at its lower end with a head 44 which is pivotallyv mounted upon a cross pin 45 in a recess 46 in the rear portion of the stock, the upper end of the hammer being provided with a finger piece 47 whereby the hammer may be swung back about its pivot against the tension of a tension spring 48 which is connected at its upper end to a pin 49 within the recess 46 and at its lower end to an. ear 50 formed at the rear edge of the head 44. The head of the hammer is indicated by the numeral 51, and, in the retracted position of the hammer, occupies substantially the position shown in Figure 3 of the drawing with respect to the firing pin 38. he hammer is provided with an abutment lug 52 at the forward side of its head 44, and the numeral 53 indicates a rack bar which is slidably mounted in one side of the recess 46 and is provided at its rear end with a laterally projecting lug 54, which is, in one position of the rack bar, located below the abutment lug 52 upon the hammer so as to hold the hammer in its retracted position as shown in Figure 3. This abutment lug 54 also constitutes a part by a finger ly from the trigger of the rifle which trigger is indicated by the numeral 56, and is pivotally mounted, as at 57, inthe lower portion of the recess 56, the finger piece of the trigger being indicated by the numeral 58 and the trigger guard by the numeral 59. The

head 44 of the hammer 43 is formed in its lower side with a notch indicated by the numeral 60, and a pawl 61 is pivotally mounted as at 62 upon the head of the trigger 56, and is yieldably held by a spring 63,7in en:

extending forwardgagement at its toothed end 64 with the periphery of the head 44 so as to be engageable in the notch when the parts are in the position shown in Figures 3 and 13 of the drawings.

The rack bar 53 is provided with an upwardly offset rearward extension indicated by the numeral 65, and this extension slides in a groove 66 formed in one side wall of the recess 46, and the said rack 53 meshes with a pinion 67 which is rotatable about a spindle 68'mounted vertically in a forward extension of the recess 46, a ratchet 69 being fixed with respect to the pinion 67 for rotation therewith, and a pawl 70 is mounted upon the pinion 67 at the upper side thereof and yieldably held, by a spring 71, in engagement with the ratchet 69. At its upper side the ratchet is provided with spaced lugs 72 radial to the axis of the ratchet and these lugs engage in sockets 7 3 formed in the under side of a pin wheel 74 which has a series of pins or studs 75 projecting from its periphery to engage in socket-s 76 formed in the rear face of the rim of the drum 13. At this point it will be evident and particularly by reference to Figure 3 that when the trigger is pulled, the rack bar 53 will be shifted forwardly thus first cocking the hammer 47 from its neutral position shown in Figure 3, and then releasing the hammer by disengagement of the pawl 61 from the notch 60, and as the lug 54 moves forwardly, the pinion 67 will be rotated. as also the ratchet 69 and the pin wheel 74 will likewise be rotated so as to rotate the cartridge supporting drum a distance of one of the cartridge housing chambers 21 or 21, as the case may be and bring this chamber and the cartridge therein into position for impact of the cartridge cap by the firing pin, when the hammer is released.

In, order to prevent any rotative displacement of the drum 13 after it has been rotated one step in its rotative movement, as above described means is provided which will now be described.

The means referred to comprises a detent lever 77 which is pivotally mounted as at 78 within the recess 46 and extends through the forward extension of the recess, and with its end located within the bounds of the rim 14 of the cartridge carrying drum, a tooth '7 9 being carried at the end of the detent lever andcengageable successively in an annular series of sockets 80 formed in the inner side of the said rim, A tension spring 81 is connected atone point to a fixed element upon theside wall of the recess 46 and at its outer end to the upper side of the detent lever 77 slightly rearwardlyof its pivot 78 and the detent levergis provided in rear of its pivot with a finger-,indicated by the numeral 82 and the end of this finger rests upon the extension 52 of the hammer 43, and, when the hammer is cocked this extension 52 riding 1 lug upon the rack,

upwardly will efiect rocking movement of the detent lever against the tension of the spring 81 to retract the tooth '2'9 from the socket 80 in whichit is at that time engagedto release the cartridge drum for rotation to bring a fresh cartridge into pos tion opposite the firing 1313,116Xt, the rack bar 53 1s retracted and the pinion 67 is reversely rotated to etiect rotation, for a part otarevolution of the pin Wheel 74 to bring 1n one oi the pins 75 upon said wheel, into engagement with the socket 76, next in order in the $815165.
